LAUNCHXL-F280049C: PWMDAC0/1 EPWM8A/B pin map card & schematic conflicts with SDK hal.c

Part Number: LAUNCHXL-F280049C

Has there been an update to the 49c lanuch pad PDF ( tSPRUII7A–June 2018–Revised March 2019) to properly indicate booster header pins J6 GPIO pins 14/32, respective EPWM-8A/B? Where is EPWM-7A/B on J6, hal.c has two EPWM8B GPIO noted?

Also there are no PWM-DAC4 GPIO output pin/s defined in SDK 3.01.00.00  hal.c.

So EPWM-8B is configured for GPIO pin 15 but booster header pin map card and schematic both show pin 32, very confusing.

    BTW: There is missing sub-module discussion for xBAR SD1FLTx (PWMDACx) functionality. Other than very limited xBAR MUX configuration as noted in SPRUI33C–November 2015–Revised August 2019

    Not clear what you're asking about regarding GPIO14/32 on the User / Quick Start Guide.

    I'd suggest using the Pinmux tool to identify C2000 signal locations on the LaunchPads.

    https://dev.ti.com/sysconfig/?fromPinmux=true#/start

    The F28004x LaunchPad does not have PWM DAC signals (i.e. filtered PWMs).

    Best,
